Price by linear foot and home height.
Most professional companies charge between $0.80 and $2.50 per linear foot. For a standard 2,000 sq ft home with roughly 160 feet of gutters, you should expect to pay between $160 and $400 depending on debris levels and house height.
National averages range from $0.80 to $2.50 per linear foot. If a home has gutter guards, don't assume the job is easier; removing and cleaning under guards often takes 2x longer than open gutters.
Always apply a height multiplier for 3-story homes. The risk and time required to move 32-foot extension ladders safely adds significant overhead to the project.
